feat: add password reset functionality

- Implement PasswordResetsController with new and create actions
- Add views for new and edit password reset forms
- Update routes to include password reset paths
- Create migration to add reset_digest and reset_send_at to users

This commit introduces a complete password reset feature, allowing
users to request a password reset via email. It includes the
necessary controller actions, views, and database schema updates.
The user experience is enhanced with a link to the password reset
form on the login page.
